LUBRICATOR FOR ELEVATOR-GUIDES.

Specification of Letters Patent.

' Patented Nov. 1, 1910.

Application filedDecember 23, 1909. Serial No. 534,608.

To all whom it may concern:

Be it known that I, CHARLES V. lVAnRnN, a citizen of the United States,and a resident of Cambridge, in the county of Middlesex and State ofMassachusetts, have invented a new and Improved Lubricator forElevator-Guides, of which the following is a full, clear, and exactdescription.

The invention is an improvement in lubricators for elevator and similarguides, and has in view such a device which will feed the oileconomically, yet keep the guide sufliciently and substantiallyuniformly lubricated, the lubricant being prevented from otherwisewasting, as by slopping or by spattering over the top of the cup.- Tothis end I provide a lubricant cup having a wick tube leading therefrom,the cup being otherwise normally closed, with the discharge end of thetube arranged above the oil level in the cup, a guide in which the tubeis slidably arranged, and means yieldingly forcing the cup and tube in adirection to press the wick against the elevator guide, the arrangementof the cup being such as notto interfere with the movement of the tubein the guide in either direction.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the views.

Figure l is a side elevation, partly in central vertical section, of alubricator embodying my invention as applied to an elevator; and Fig. 2is a plan of the lubricator, showing the elevator guide in section.

A lubricant cup or tank 5 of suitable capacity is provided with alaterally-extending wick tube 6, the tube being preferably connected tothe upper portion of the cup above the oil level, it being essentialthat the discharge end of the tube stand above this level in order thatthe oil will flow out only through the capillary action of the wick 6the wick being preferably of cotton, as I have found a wick of thischaracter to give the best results, since it does not become glazed andcut oil the flow of oil, as does a wick of felt or similar material. Thetop of the cup is provided with a fillingplug 8, which is screwed toplace when the lubricator is in use, thus giving no opportunity for theoil to slop over. The wick tube 6 is rigid with the cup and is slidablyarranged in a guide tube 7, the latter being carried on a suitablesupport 8 which is attached to the car 9, ordinarily at the top, withthe guide tube a short distance from the elevator guide 10, and locatedapproximately horizontally in a plane therewith. The cup and wick tubeare yieldingly pressed to the guide to keep the wick well in contactwith the inner face of the latter, by a spring 11, this spring beingpreferably applied by connecting one end to the wick tube 6, as throughan eye 12, and the opposite end to the guide tube 7 the eye beingsuitably attached to the wick tube and passing through a slot 13 formedlongitudinally in the guide tube and serving to prevent the rotation ofthe cup, with the wick tube as an axis. This manner of constructing thelubricator places the oil cup at a substantial distance from thedischarge end of the wick and insures the economical use of thelubricant, no substantial feeding of the latter taking place when thecar is at rest.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A lubricator for elevator guides, comprising a lubricant cup having awick tube extending therefrom, a tubular guide carried by the elevatorcar, in which the wick tube is slidably arranged, an eye attached to thewick tube and extending through a slot formed in the guide tube, and aspring having one end attached to the guide tube and its opposite endengaged in the eye.

2. A lubricator for elevator guides, comprising a lubricant cup having awick tube, the wick tube discharging laterally from the cup, a wickextending through the tube from the cup and feeding the lubricant fromthe cup by capillary action, a guide carried by the elevatorcar, onwhich the wick tube is slidably arranged to move to and from theelevator guide, and a spring arranged to hold the outer end of the tubeoperatively to the elevator guide, with the cup and guide located whenin operative position to permit of the sliding movement of the tube ineither direction.

3. A lubricator for elevator guides, comprising a wick tube, a guidecarried by the elevator car, on which the wick tube is slidablysupported to move to and from the ele- Vator guide, a lubricant cupsupported on the wick tube and from which the wick tube laterallyextends, and a spring to hold the outer end of the tube operatively tothe elevator guide, having one end connected to vator guide, having oneend fixed relatively the guide and the other end engaged with to theguide and the other operatively enthe tube. gaged with the tube throu hthe said slot.
